Chifukwa chiyani chosinthira mpweya chiyenera kukhala ndi chitetezo chokwanira komanso chitetezo chachifupi

Chophimba cha Air (chomwe chimatchedwa "air switch", apa tikunena za GB10963.1 yokhazikika yamagetsi yapanyumba) chinthu chodzitchinjiriza chimakhala chingwe, funso lalikulu ndilakuti "chifukwa chiyani chosinthira mpweya chiyenera kukhazikitsa chitetezo chodzaza ndi chitetezo chachifupi" ikhoza kukulitsidwa ku "chifukwa chiyani chingwecho chiyenera kuyika chitetezo chokwanira komanso chitetezo chachifupi nthawi imodzi"

1.Kodi overcurrent ndi chiyani?

Mphamvu ya loop yomwe ili yokulirapo kuposa momwe ikunyamulira pakalipano ya loop conductor imakhala yochulukirapo, kuphatikiza pakali pano komanso nthawi yayitali.

2.the chingwe overload chitetezo

Kuzungulira kwamagetsi chifukwa cha zida zamagetsi zambiri kapena zida zamagetsi zomwe zimachulukira (monga kuchuluka kwamakina agalimoto ndikokulirapo) ndi zifukwa zina, mtengo wapano ndi nthawi zambiri zomwe zidavotera dera, zotsatira zake ndikuti kutentha kwa chingwe kumapitilira mtengo wololeka, kutchinjiriza chingwe kumathandizira kuwonongeka, kufupikitsa moyo.Mwachitsanzo, pazingwe za PVC, kutentha kwakukulu kololedwa kugwira ntchito kwa nthawi yayitali ndi 70 ° C, ndipo kutentha kovomerezeka kwa nthawi yochepa sikudutsa 160 ° C.

Chingwecho chimatha kupirira kuchulukira kwina kwanthawi yayitali, koma nthawiyo iyenera kukhala yochepa.Ngati kuchulukiraku kumatenga nthawi yayitali, kutsekereza kwa chingwe kumawonongeka, zomwe pamapeto pake zingayambitse vuto lalifupi.Kutentha kwa gawo la kutchinjiriza kwa chingwe pansi pakalipano, mochulukira, komanso nthawi yayitali.

Choncho, mu mtengo wamtengo wapatali wa chinthu chophwanyira dera, woyendetsa dera amafunika kukhala 1.13In, kuchuluka kwamakono sikukugwira ntchito mkati mwa ola la 1 (In≤63A}), ndipo pamene panopa atsegulidwa pa 1.45In, kuchuluka kwake mzere uyenera kuchotsedwa mkati mwa ola limodzi.Kuchulukirachulukira panopa amaloledwa kupitiriza kwa ola 1 kuganizira kupitiriza kwa magetsi ndi chingwe palokha ali ndi zina mochulukira mphamvu, sangathe pang'ono odzaza mzere, wosweka dera adzadula mphamvu, zomwe zidzakhudza yachibadwa. kupanga ndi moyo wa okhalamo.

Chinthu chotchinjiriza cha wowononga dera ndi chingwe.Pazifukwa zochulukirachulukira, kuchulukitsitsa kwanthawi yayitali kumapangitsa kutentha kukwera, zomwe zimapangitsa kuwonongeka kwa chingwe chotchinga, ndipo pamapeto pake kulakwitsa kwafupipafupi.

Pafupipafupi dera nyengo, kutentha adzauka mu nthawi yaifupi kwambiri, ngati si kudula mu nthawi, kungachititse kuyaka mowiriza wa wosanjikiza kutchinjiriza, monga gawo chitetezo cha wosweka dera, onse zimachulukira chitetezo ntchito, komanso amafunikira yochepa. ntchito yoteteza dera.
